概要
Description
S29GL032N90TFI020 is a Spansion/Cypress 32-Mbit NOR flash memory device. Key points:
- Density: 32 Mbit (4 MB) of non-volatile storage.
- Voltage and speed: 3.0 V operation (typical 3.0–3.6 V) with a 90 ns read access time.
- Interface: Parallel NOR flash with the standard command set (Read, Page Program, Block/Sector Erase, etc.).
- Features: Block/sector erase, page programming, status/protection features (block locking), and typically a software/timeout status polling mechanism.
- Packaging: Delivered in the TF I020 package variant (specific form factor/pinout per datasheet).
- Applications: Firmware and code storage for microcontrollers and embedded systems requiring reliable, fast random access and in-system programming.
Note: Check the official datasheet for exact block sizes, page size, voltage ranges, timing specs, and packaging/pinout details.
